Mike Portnoy launched a songwriting competition over his website, where he posted the song's arrangement chart before it was released, and invited the fans to record their own versions of Stream of Consciousness based on what was written on the chart. The results were later released on a fan club CD.
Like most of the songs on Train of Thought, Stream of Consciousness has a dark and heavy tone to it, with the intro having an unexpectedly loud start. The song is also very progressive, with many meter changes and several solo sections included in the song. The outro is very melodic and epic, climaxing with a dual guitar solo and a reverse of the clean guitar intro.
The song is a popular inclusion in Dream Theater's live shows and appears on the live album Live at Budokan.
